Deploying with JRuby--New from Pragmatic Bookshelf: Deliver Scalable Web Apps using the JVM

Deploying with JRuby

Request Review copy

Raleigh, NC—Writing Ruby on Rails apps, but having problems deploying using traditional Ruby tools? JRuby is a fast, scalable, and powerful JVM language with all the benefits of a traditional Ruby environment. Now you can deploy using the JVM's high performance while building your apps in the language you love, using Deploying with JRuby: Deliver Scalable Web Apps using the JVM (Pragmatic Bookshelf, $33.00 USD).

Author Joe Kutner says, "JRuby deployments have fewer moving parts and consume less memory than traditional Ruby deployments, but to deploy your apps on the JVM, you need to learn some new approaches." This book introduces you to three JRuby deployment strategies that will give you the performance and scalability you need while still working in RubyŚno Java or XML required.

You'll start by porting an existing application to JRuby, preparing the app to take advantage of the JVM platform. Then you'll use Vagrant and Puppet to build a virtual production environment so you have a stable, reproducible place to explore JRuby deployment.

With your environment in place, you'll experiment with simple JRuby deployment with Warbler as you package your Ruby web application into a single file you can deploy to a Java application server. Next you'll set up the lightweight Trinidad web server to create a more flexible, modular deployment that fits more complex situations but still feels friendly and familiar to Ruby developers. You'll switch to powering your app with TorqueBox, an all-in-one JRuby environment that includes built-in support for messaging, scheduling, and daemons—perfect for handling the "big jobs." Then, you'll set up a continuous integration environment with Jenkins so you can deploy like the pros.

Deploying with JRuby is the missing link between enjoying JRuby and using it in the real world to build high-performance, scalable applications.

Available for e-readers in epub, mobi, and PDF formats direct from the publisher and in paperback from fine bookstores worldwide.
